I actually made it 2.5 years ago, but I never formally open sourced it, more forgot about it, actually. When at the Krita sprint, Boudewijn remarked he really disliked the way how webcomics present themselves, I remembered it again and show it to him and Timothée Giet. Timothée, as a comics creator was interested in using it, and I finally took the step to open source it.
